I have a city-wide LiDAR (LAS format) dataset that I'd like to clear of outlier points to process in ArcMap 10.7. I've identified the points using the Locate Outliers tool.

How do I use the resulting point feature class to rid the point cloud of those points?

I understand it's possible with LasTools in ArcGIS Pro, but I do not have access to it.

It's not ArcMap, but it is straightforward to identify noise (classification == 7) and remove it in a pdal translate operation:

pdal translate input.las output.las lof range --filters.range.limits="Classification![7:7]"

PDAL can be installed into your ArcMap Conda environment by using the Conda Forge channel. See more about installing PDAL in from Conda here.

  • Thanks! That's an interesting approach- however I ended up implementing the lasheight tool from LAStools in ArcMap using the Iterate Files tool in ModelBuilder.
